Connecting the power
When using a computer (Windows/Mac)
Normally, when this unit is connected to a computer, it will
operate using USB bus power, so connecting a separate power
supply device is not necessary.
When using an iOS device
When this unit is connected to an iOS device, connecting an ex-
ternal battery, USB power adapter or other power supply device
is necessary in order to power the unit.
Connect an AC adapter (TASCAM PS-P520E), external battery
pack (TASCAM BP-6AA) or the genuine Apple USB power adapt-
er included with the iPad/iPhone to a USB cable (sold separate-
ly), and connect it to the DC IN 5V port.

i No USB power adapter is included with an iPod touch. To use
it with an iPod touch, purchase a genuine Apple USB power
adapter (that can supply 5 V and a current of at least 700 mA)
separately.
i Operation with other external battery packs and USB power
adapters is possible, but we strongly recommend using a TAS-
CAM PS-P520E AC adapter, TASCAM BP-6AA external battery
pack or the genuine Apple USB power adapter included with
the iPad/iPhone.
When using another external battery pack or USB power
adapter, be sure that the power supply device meets the fol-
lowing specifications.
oSupplied voltage: 5 V
oSupplied current: 700 mA or more
Using a power supply device when the specifications are
other than the above could cause malfunction, overheating,
fire or other problems. If anything abnormal occurs, stop use

system operations, clicking and popping noises might occur
and the audio signal might even drop out.
Increasing the buffer size will stabilize operation and sup-
press negative effects on audio signals, but the delay in audio
signals sent to the computer will increase.
You can adjust the buffer size according to the use condi-
tions.

1 IN 1 volume slider
Use to adjust the volume input through the unit's IN1 jack.
2 Input selection
Use to set whether the input signal is handled as “Mono” or
“Stereo”.
Options
Mono
When using one mic (connected to the IN1 jack), it will
be treated as input from both “IN 1” and “IN 2”.
The audio from “IN 1” will be heard from both left and
right headphone channels.
In most circumstances, select this when using a mic for
a live broadcast, for example.
Stereo
Even when using one mic (connected to the IN1 jack),
it will not be treated as being input from both “IN 1”
and “IN 2”.
It will be treated as only being input from “IN 1”.
The audio from “IN 1” will be heard from the left head-
phone channel, and audio from “IN 2” will be heard
from the right headphone channel.
Use this if a keyboard or other stereo audio sources is
being input for live broadcasting or karaoke.
NOTE
When DAW mode is selected, if set to “Mono”, this will auto-
matically be switched to “Stereo”.

6 Output
Use to set whether the output signal is handled as “Mono” or
“Stereo”.
Options
Mono
Only the audio from the left side can be handled when

like this, audio from the right side cannot be transmit-
ted or recorded.
Set to “Mono” to mix both left and right signals to
mono and transmit that sound to the computer.
Stereo
Set when the application being used supports stereo.
When set to “Stereo”, a stereo sound can be transmit-
ted to the computer.
NOTE
When set to “Mono”, all stereo input signals will be converted
to mono. This setting receives priority even if the “Input” se-
lection (2) is set to “Stereo” for mic input.
7 Mic Monitor selection
If the “Mic Monitor” checkbox has a check, sounds from mic
and other input will be mixed with the “PC Audio Out” signal
and looped back to the computer.
If the check is removed from the “Mic Monitor” checkbox,
sounds from mic and other sources input through IN 1 and
IN 2 will not be sent to the headphone output.
8 Loopback selection
If the “Loopback” checkbox has a check, the sound from the
computer will be broadcast and output from the PHONES
jack.
If the check is removed from the “Loopback” checkbox,
the sound from the computer will only be output from the
PHONES jack.
